A couple noteworthy things to take note of from the Changelog.

Link Colors

The link color for text links has changed to a blue color and /darker/ of that blue color if someone visited that link.

a { }

is now

a:link { }
a:visited { }

So if you have modified link colors on your site you will need to adjust using the a:link, and a:visited as appropriate.

p.s. don’t forget

a:hover {}

for the mouse over-hover color

the menubar base color css element changed

In a previous revision I have finally fixed the menubar where it doesn’t collapse before showing. Which some people updating to .27 will notice their custom colors have changed, its a simple fix. Every instance of .menubar in your custom css change to .menu

.menubar {}

Is Now

.menu {}

New Footer text Options

Also there are new ‘footer’ text copyright options in the ComicPress Options -> [general tab][footer] area, where you can specify a specific copyright name instead of the site name and a unique / seperate URL for that copyright holder if the author has a seperate personal site other then their comic, if you leave those blank it defaults to the current site.

#subcontent-wrapper

the #subcontent-wrapper area is now available on all layout styles, although on theĀ  layouts it wasnt on previous it will only contain a section like the .narrowcolumn area instead of it and the sidebar.

Latest Thumbnail widget is now just Thumbnail

The latest thumbnail widget is now called Thumbnail where there are now a few more options.
You can now specify the 1st comic in the category you chose as well as even set it to display a random comic from the archive.

If you choose it is written that it will never display the same comic that is currently displayed on the site.
